Sliepkovce (Slovak pronunciation: [ˈslɪepkɔwtse], Hungarian: Dénesújfalu) is a village and municipality in Michalovce District in the Kosice Region of eastern Slovakia.

The colloquial Hungarian name of the current village of Sliepkovce is Dénesújfalu ("Dennis-new-ville"), apparently adopted in honour of Andrássy's support for the 1890s project.

This newer name has also become common in the Zemplín dialect of Slovak, as Deneš.

The village lies at an altitude of 105 metres and covers an area of 6.456 km².

The village has a small public library, and a football pitch, built in 1946.
